Abstract
The utility model relates to a halogen-free low-smoke cable for communication signals. The halogen-free low-smoke cable sequentially comprises a sheath layer, a fireproof layer, an armor layer, an insulation protection layer and metal wire cores from outside to inside, wherein the insulation protection layer wraps the metal wire cores; a filler is filled between the metal wire cores and the insulation protection layer; the armor layer wraps the insulation protection layer; the fireproof layer wraps the armor layer; the sheath layer wraps the fireproof layer; an insulation layer wraps each metal wire core; a shielding layer wraps each insulation layer; a polyester film wrapping layer is sleeved outside each shielding layer; each shielding layer is a meshy metal shielding layer formed by weaving tin-plated copper wires; and the metal wire cores are wire cores formed by stranding a plurality of copper cores. The halogen-free low-smoke cable for the communication signals is safe, environment-friendly, flame-retardant, fireproof, high in interference resistance and long in service life and is provided with the protection layer.
Description
Technical field
The utility model relates to the cable technology field, relates to a kind of communication signal in particular and uses the low smoke, zero halogen cable.
Background technology
Development along with information technology; Setting up with the establishment of network of communication line is also more and more intensive, and people are also more and more to the demand of communication cable, and the major function of communication cable is to be used for transmission of audio, analog signal and digital signal; The conventional structure of existing communication cable is to be coated with insulating barrier, screen and restrictive coating from inside to outside successively in the periphery of core; Screen all is metal knitted net generally, is used for stopping the radiation of outside electric wave, the normal conveying of the electronic signal stream of protection core; Its antinoise signal interference capability of this traditional cable is weak, the fire-retardant fireproof poor performance; Do not possess simultaneously safeguard measures such as protective layer, when cable is damaged, cause the paralysis meeting of communication system to cause very big inconvenience and economic loss to the user.
The utility model content
The purpose of the utility model is the weak point to prior art, provides a kind of communication signal use the low smoke, zero halogen cable, its have low cigarette, nontoxic, fire-retardant fireproof, antijamming capability by force, have advantages such as protective layer, long service life.
The technological solution of the utility model is following:
A kind of communication signal is used the low smoke, zero halogen cable, and it is provided with restrictive coating, fireprotection layer, armour, insulation sheath and metal core from outside to inside successively, and said insulation sheath is coated on outside the metal core, and metal core and insulation are filled out between the sheath and be provided with filler; Said armour is coated on outside the insulation sheath, and fireprotection layer is coated on outside the armour, and restrictive coating is coated on outside the fireprotection layer; A layer insulating is covered in the outsourcing of said metal core, and insulating barrier coats one deck screen outward, the outer sheathed one deck polyester film coating layer of screen.
In the technique scheme, said screen is the net metal screen that tinned copper wire is worked out.
In the technique scheme, described metal core is by the stranded core that forms of two or more copper cores.
The beneficial effect of the utility model is:
The cable of the utility model is provided with restrictive coating, fireprotection layer, armour, insulation sheath from outside to inside successively, is a kind of safety and environmental protection, harmless flame retardant cable, after burning, does not produce thick smoke and virose gas; Fireprotection layer can effectively be prevented fires; Armour has improved the mechanical performance and the electric property of cable, and the protection cable is not fragile, prevents to be gnawed bad by unfirmly closing or mouse; Between metal core and insulation sheath, fill out simultaneously and be provided with filler; A layer insulating is covered in the outsourcing of metal core; Insulating barrier coats one deck screen outward, and it effectively shields the interference that external disturbance and internal transmission cause, the outer sheathed one deck polyester film coating layer of screen; Improve the toughness of communication cable, strengthened the bending resistance of cable.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model.
Embodiment
The following stated is merely the preferred embodiment of the utility model, is not that scope to the utility model limits.
Embodiment; See accompanying drawing 1, a kind of communication signal is used the low smoke, zero halogen cable, and it is provided with restrictive coating 1, fireprotection layer 2, armour 3, insulation sheath 4 and metal core 5 from outside to inside successively; Said insulation sheath is coated on outside the metal core, and metal core and insulation are filled out between the sheath and be provided with filler 6; Said armour is coated on outside the insulation sheath, and fireprotection layer is coated on outside the armour, and restrictive coating is coated on outside the fireprotection layer, and restrictive coating adopts the extruding of high flame retardant cross-linking radiation elastomeric material to form, and has high flame retardant and high insulating property; A layer insulating 7 is covered in the outsourcing of said metal core, and insulating barrier adopts the weather-proof insulating material extruding of low smoke, zero halogen to form, and insulating barrier coats one deck screen 8 outward, the outer sheathed one deck polyester film coating layer 9 of screen.
In the technique scheme, said screen is the net metal screen that tinned copper wire is worked out, because zinc-plated effect is expired whole filling the in gap between the net metal silk, has strengthened the antijamming capability of screen.
In the technique scheme, described metal core is by the stranded core that forms of two or more copper cores, has intensity and ductility preferably, conducts electricity very well.
Claims (3)
1. a communication signal is used the low smoke, zero halogen cable; It is characterized in that: it is provided with restrictive coating, fireprotection layer, armour, insulation sheath and metal core from outside to inside successively; Said insulation sheath is coated on outside the metal core, and metal core and insulation are filled out between the sheath and be provided with filler; Said armour is coated on outside the insulation sheath, and fireprotection layer is coated on outside the armour, and restrictive coating is coated on outside the fireprotection layer; A layer insulating is covered in the outsourcing of said metal core, and insulating barrier coats one deck screen outward, the outer sheathed one deck polyester film coating layer of screen.
